LSP.expert does not send reminders and doesn't have a dashboard. But in the LSP.expert menu, next to the Settings tab, there is a little bell icon for what we call the 'alerts'.

When you click on it, a pop-up opens telling you which jobs, invoices and quotes are due today or overdue.
Blue: The due date is today.
Red: The quote/job/invoice is overdue.
Green (only for jobs): means that the job is ready to be started (when a start date has been defined).

There is a red number next to this bell to indicate how many 'alerts' you have for the day. If there are more than 9 alerts, the number will be replaced by a '+'.
